Evaluation of Synthetic Data Classification performance on the test split of the Spatial Heterogeneity synthetic dataset, using specific parameters ps(r)=(0.999, 0.9, 0.8, 0.7) and pv=0.9. Metrics include Test Mean Accuracy and Test Worst Accuracy.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Synthetic Data Classification |
| Dataset (including any stated split) | Spatial Heterogeneity (ps(r)=(0.999, 0.9, 0.8, 0.7), pv=0.9) synthetic (test) |
| Metric | Mean Accuracy |
| Unit | PERCENT |
| Direction | Higher is better |
| Results loaded | 5 of 5 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.
